In the "file content" property you should put the Input FileName Widget's content, by default it is "InputFilename1.Content", you should also validate if the user really chose a file or not (InputFilename1.Filename <> "", this is a simple test but doesn't prevent empty files! But it should be enough to get through this stage) .

I have a " Attach Documents " button in my web page creation. I should know how to connect it with the local drive and web too as in mail all ( i.e attach button which displays options like images , pdf , files , videos , contacts , download from server etc... ) .
